The native structure of the activated Raf protein kinase is a membrane-bound multi-subunit complex.
Open accessAbstract
Raf is a mitogen-stimulated protein kinase that functions as a component of the signaling cascade that leads to the stimulation of mitogen-activated protein kinase. Here we show that the native structure of Raf is a large multi-subunit protein complex with an apparent mass of 300-500 kDa that interacts with Ras and the mitogen-activated protein kinase kinase Mek. Analysis of the structure of the Raf complex demonstrates that it contains a single Raf protein kinase together with the molecular chaperones hsp90 and p50. The Raf-hsp90-p50 complex was observed in starved cells and in cells activated with serum or phorbol ester. Thus, changes in complex formation with hsp90 and p50 are not required for activation of the Raf protein kinase. However, Raf activation caused by Ras was associated with the translocation of the cytoplasmic Raf-hsp90-p50 complex to the cell membrane. Significantly, it is only the membrane-bound complex that exhibits increased protein kinase activity. Thus, the Ras-activated Raf protein kinase functions as a membrane-bound multi-subunit complex.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
